Dynamic Validation: Transit Level of Service Changes

Transit Frequency Doubled Systemwide

In this dynamic validation test, frequency of all transit services is doubled. This is achieved by halving the headway in the transit route system file. The model was run with this update and the resulting highway loading is shown in the map below on the right. The base year highway loaded result is shown on the left for comparison. Table 1 shows the transit boardings by route for the base scenario and for the frequency doubled scenario.

Table 1: Boardings comparison

Route Desc	Base Year Boardings	Frequency Doubled Boardings
20	7.20	12.00
23	137.80	169.00
267 - Highway 267 Route	22.83	39.09
50	9.00	26.00
53	288.00	416.29
53 - Late Night	116.00	145.00
53 - LTCC	144.00	138.79
89 - TART Hwy 89 Route	13.00	24.50
East Shore Express	0.00	0.00
ML - TART Mainline	1090.20	1441.15
PM TART Night Service	132.97	176.26
Total	1961.00	2588.08

Key insights from this dynamic testing is summarized below:

• The transit boardings increased from 1,961 to 2,588, an increase of 32%.

• The region wide VMT decreased by 3,574 miles, a decrease of 0.11%.
